NOTICE
To avoid the possibility of malfunction/ damage to the product, or
damage to other property, follow the notices below.
Handling and maintenance
•Do not use the device in the vicinity of a TV, radio, stereo
equipment, mobile phone, or other electric devices. Otherwise,
the device, TV, or radio may generate noise.
•Do not expose the device to excessive dust or vibration, or
extreme cold or heat (such as in direct sunlight, near a heater,
or in a car during the day), in order to prevent the possibility
of panel disfiguration, unstable operation, or damage to the
internal components.
•Do not place vinyl, plastic or rubber objects on/under the
device, since this might discolor the panel of the device or the
objects placed on/under the device.
•Keep input cables of microphone, etc., devices that contain
sensitive circuits, and the power cord at a distance from
speaker cables and fasten the speaker cables in place.
Since a large amount of current can flow in a speaker cable,
a magnetic field will be generated and may produce radio
interference and acoustic noise.
•When cleaning the device, use a dry and soft cloth. Do not
use paint thinners, solvents, cleaning fluids, or chemicalimpregnated wiping cloths.
•Condensation can occur in the device due to rapid, drastic
changes in ambient temperature–when the device is moved
from one location to another, or air conditioning is turned
on or off, for example. Using the device while condensation
is present can cause damage. If there is reason to believe
that condensation might have occurred, leave the device
for several hours without turning on the power until the
condensation has completely dried out.
•Avoid setting all equalizer controls and faders to their
maximum. Depending on the condition of the connected
devices, doing so may cause feedback and may damage the
speakers.
•Do not use this device for any purpose other than driving
loudspeakers.
•When turning on the AC power in your audio system, always
turn on the device LAST, to avoid speaker damage. When
turning the power off, the device should be turned off FIRST for
the same reason.
•If you put the device on a table or a rack, do not remove the
rubber feet from the device.
•Always turn the power off when the device is not in use.
Connectors
XLR-type connectors are wired as follows (IEC60268 standard):
pin 1: ground, pin 2: hot (+), and pin 3: cold (-).
Precautions for rack mounting
This unit is rated for operation at ambient temperatures ranging
from 0 to 40 degrees Celsius. If the device is mounted with
other devices in an EIA standard equipment rack, internal
temperatures can exceed the specified upper limit, resulting in
impaired performance or failure. If the device is mounted in a
rack, always observe the following requirements to avoid heat
buildup:
•If the device is mounted in a rack with other devices that
generate a significant amount of heat, such as a power
amplifier, leave more than 1U of space between the device
and other devices (both above and below). Also, make sure to
either leave any open spaces uncovered or install appropriate
ventilating panels to minimize the possibility of heat buildup.
•To ensure sufficient airflow, leave the rear of the rack open and
position it at least 10 centimeters from walls or other surfaces.
If you’ve installed a fan kit, there may be cases in which
closing the rear of the rack will produce a greater cooling
effect. Refer to the rack and fan unit manual for details.
